Students will be presented with an overview of health and disease followed by a set of tools for disease prevention and control. They will especially be encouraged to reflect on the importance of epidemiology and surveillance systems (for disease as well as health and for risk factors). They will be tasked with the application of these tools to the prevention and control of a number of important (for South Africa) health threats, both infectious and non-infectious. The scope will be all disease conditions including psychiatric, trauma, violence, etc in addition to the conventional inclusion of infectious diseases and diseases of lifestyle. There will be a link, too, to the concept of “implications for policy”.
